{eMac} Super Drive

Where is a good place to buy a new super drive for a eMac? I am having trouble with mine, because it doesn't want to read double layer dvd's and I want to reinstall the OS on it. I know that its a problem with the drive cause I spoke with apple on it. So any good sites for affordable drives will help.
